Description: I saw 2 round balls high in the sky traveling side by side in unison. They were traveling south when they both stopped and were motionless in the sky. The round black ball was slightly ahead of the round silver ball. They stayed in the same position for a long time. Around December I saw the same silver ball in the sky in one fixed position by itself. It was also a semi hazy day. I was transfixed with both sightings. The silver ball zoomed across the sky in a straight line and was gone! I have never seen anything move like that before.
